Title: Character generation system
Inventor: MICHI YOSHIYUKI
IPC: G09G1/00
Filed: 1979-02-28
Abstract: PURPOSE: To reduce memory capacity by subordinating character expanding- contracting circuits of the best algorithm to respective pattern generators by grouping various characters on the basis of the number of strokes of each character and then by storing them in character generators.  
     CONSTITUTION: Read character codes from terminal 2 are inputted to character conversion table 1. Table 1 decodes each character code to judge which of addresses of character pattern generators G 1 , G 2 ... a corresponding character pattern is stored, thereby attaining access to the character pattern generator. Generators G 1 , G 2 ... are stored with groups of characters classified by the number of character strokes. Then, the accessed character pattern is passed through character expanding-contracting circuits C 1 , C 2 ... which are subordinate to the group and have the best algorithm for the expansion and contraction of the pattern of the group, so that an expanded or contracted character pattern signal will be outputted from terminal 3. Consequently, the expanded or contracted character of good quality can be obtained and memory capacity is lessened in comparison with the providing of a pattern of each size.

Title: Phase locked loop circuit
Inventor: SUZUKI EIJI
IPC: H03L7/18
Filed: 1988-02-03
Abstract: PURPOSE:To prevent transient phenomenon from being occurred in the changeover of a band width of a loop by providing the 1st frequency division means frequency-dividing into n to an input, outputting the result of giving direct output. CONSTITUTION:The 1st frequency division means 2 frequency-divides into n to an input signal by a switching signal from a synchronizing detection means 4, gives an output or outputs the signal directly. The 2nd frequency division means 5 frequency-divides into n to an output signal of a voltage controlled oscillator 13 by a switching signal from a synchronizing detection means 4, gives an output or outputs the signal directly. When the synchronizing detection means 4 detects the synchronization of the output of the voltage controlled oscillator 13 with the input signal, a switching signal is sent to the 1st and 2nd frequency division means 2, 5 to apply the result frequency-divided into n to the input signal and the output of the voltage controlled oscillator 13. Thus, the modulation sensitivity is 1/n than before synchronization and the band width of the loop is made narrow. Thus, since the input/output characteristic of the phase detector 3 is kept as it is at switching, no transient phenomenon takes place.

Title: Formation of thin film
Inventor: WATANABE MIYOKO
IPC: C30B25/18
Filed: 1995-02-13
Abstract: PURPOSE: To form a good-quality BCN thin film on a substrate with the surface insulated at the time of forming >=1 layer of the thin film of layer structure shown by Bx Cy Nz on the substrate by using hexagonal boron nitride as the substrate. CONSTITUTION: The hexagonal boron nitride (h-BN) has 0.2504nm interasurface lattice constant conforming almost to the lattice constants of various BCN thin films, and hence the boron nitride is ideally used as a thin film forming substrate. Meanwhile, the h-BN is stable to the high temps. of >=2000 deg.C, and B and N are not desorbed from the surface. Consequently, the substrate can be cleaned at a temp. higher than 800-900 deg.C, and the cleaned surface is exposed by cleavage, since the h-BN is a layered substance. Further, the thermal expansion coefficient of the h-BN is 7.7×10<-7> which is very close to the 1×10<-6> of BC2 N, for example, and hence the generation of strains due to the temp. change in the thin film growth is suppressed.  The substrate and thin film are typically shown in the figure, and a thin film 22 of layer crystal structure having about 0.15μm thickness and with the surface flattened is formed on the h-BN substrate 21.
